DECARBONIZATION (CONT.)
• Indicators of Federal support
• America’s Transportation Infrastructure
Act (ATIA) – federal funding bill
• $10 Billion “climate title”
• Formula grants
• Discretionary grants
• Increase in funding for non-motorized
transportation
• FHWA guidebook for state DOTs on
emissions reductions (by end of CY 2020)
Key Takeaways from FHWA:
• Most emissions reductions will come from clean vehicle and fuel technologies
• Demand reduction and systems efficiency strategies can reduce emissions another 5-20%
• Additional 2-3% reduction potential from DOT construction materials, fuels/fleets, and buildings
• GHG reduction targets of 75-80% by 2050 are challenging and will require widespread electrification and clean grid
• Most strategies require implementation at multiple levels (state, regional, local)

and fleets
• Implement ITS/efficient traffic operations
• Support alternative modes of transport to
reduce VMTs, reduce employee VMTs wherever
possible (i.e., encourage teleworking)
• Adjust office building thermostats
• Use low-carbon, recycled/reused construction
materials where feasible
• Collaborate with other state, regional, and local
agencies to do everything within collective power
What are other state DOTs doing?
• Minnesota:
• Reducing facilities emissions (building thermostats)
• Prioritizing electric vehicles
• Washington State:
• Reducing VMTs, reducing congestion
• Promoting vehicle efficiency, electric vehicles, biofuels
• Texas
• Drive Clean Texas campaign, toll credits for EV drivers
• Teleworking, shortened work weeks for TXDOT employees
• Clean operations: solar sign boards instead of diesel
• Sustainable pavements: “warm mix” instead of hot mix asphalt, pavements with recycled products
• Alternative fuel vehicles, electrifying corridors

Enhancement of Stormwater Infiltration, Water Retention, Nutrient Removal, and Plant Growth in Bioretention Media
Through Biochar Amendment Paul Imhoff, University
• Study used a mix of biochar (think Kingsford but pellets) and sawdust, and other media to test the ability of the biochar to remove nutrients
• Delaware mix, North Carolina mix and ratios of biochar in study
• Biochar increased phosphate leeching in bioretention mix overall, greater infiltration in NC biochar study
• Secondary study on plants and bioretention media after creating labd“drought” conditions
• NC mix plants better suited and survived “drought” study
